If it's rechargeable, then it will have a shortened life, because a 1.8Ahr capacity is far from optimal for a load of more than an amp.FAQ: How can I calculate the time it would take for my battery to run down? How long does a battery last on average?
1. Calculate the current I_1, I_2, and I_3. 2. Calculate the total power dissipated in this circuit. How to convert miles to kilometers with a formula How do you convert kilometers to miles with a formula? The power of an isotropic radiation source is 767 kW. Calculate the intensity...
of ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium then the it's membrane potential is equal to the Nernst ...
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article onhow to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric ...
Here's my battery hooked up to a flashlight bulb to make a simple circuit. I've unwrapped a paperclip to make a piece of connecting wire and I'm holding that between the bottom of the battery and the side of the bulb. If you look closely, you can see the bulb is shining. That'...
Using the Nernst equation, one can calculate the EMF produced under a no-load situation: Where E is the Nerstian EMF generated, R is the Universal Gas Constant = 8.31 J*K-1*mol-1, T is the temperature of the cell in Kelvin, F is the Faraday Constant = 96500 Cmol-1, Z is the ...
A 7.0 ohm, a 13 ohm and a 10.0 ohm resisitor are connected in series with a 12.0 V battery. (a) Calculate the equivalent resistance. (b) What is the current in each resistor? Three resistors of 12, 12, and 6.0 ohm are connected in parallel. A 12-V...
